About the Webinar

This webinar explores the replacement of iron oxide black with ultramarine blue in foundations for North Asian skin. The study achieved equivalent color matching
(ΔE00 <1) while enhancing cosmetic benefits. Expert evaluations demonstrated improved skin uniformity, better wrinkle concealment, and reduced visible imperfections. Spectroscopic analysis further revealed that ultramarine increases red light reflection, contributing to a more radiant skin appearance. This research introduces a novel approach to color matching and formulation innovation in cosmetics.
